The social network of classmates continues to invent more and more new ways of monetization. At this time charges have decided to do . . . smiles. In the window sending the message to another user, you can see a set of emoticons, which, incidentally, was not too original. When I try to select any character from this set of window appears with a proposal to pay for the opportunity to upload their own emoticons and add other users. Payment is made for the usual classroom method - via SMS. The most interesting thing is that the service is provided as a subscription. One paid a message provides an opportunity to use emoticons 45 days, after which you will need to pay again.
